Corrosion of first degree of right foot, initial encounter

This code signifies a first-degree burn, specifically a corrosion, affecting the right foot. A first-degree corrosion involves only the outermost layer of skin (epidermis), typically presenting with redness, mild swelling, and pain without blistering.

This code is appropriate for initial encounters where a patient presents with a chemical burn to the right foot that is superficial and does not involve blistering. This would include exposure to corrosive substances causing epidermal damage.

• Ensure the documentation clearly specifies "corrosion" rather than "burn" if a chemical agent is involved.
• Verify the laterality (right foot) and the degree of corrosion (first degree) are explicitly stated.
• Confirm this is the initial encounter for this specific injury; subsequent care would use a different encounter character.
